To all zul/hom, t mwyoneen.- Beit known that We, ALBERT DELLAMORE,

SAMUEL T. NORTON, and ALBERT M. NOR- T'ON, citizens of the United States, residing at Los Angeles, in the county of Los Angeles,

State of California, have invented certain l new and useful Improvements in Apparatus turing land mixing of dry hydraulic plaster,'

for Mixing and Making Plaster andy Mortar,

of which the following is a description, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

Our invention relates to and deals with the l.

production and mixing of common plaster andv mortar composed of lime, sand, water, and fiber, as distinguished from the manufacmortars, and cements.y It also deals with the manufacture of plasteroand lmortal' upon a commercial scale and'in large quantities by the aid of al complete apparatus or set of machines for handling, proportioning, and mixing the ingredients of mortar, and thereby economically obtaining a constant, uniform, and superior product, as opposed to the -Wellknown `manual manufacture and mixin of plaster and mortar inthe street mortared and to operations in no step of which is machinery employed.

Our lnventlon consists 1n certain combination of machines and instrumentalities hereinafter described and claimed.

=Brieiiy stated, our invention comprehends an a in w ch the lime is first t oroughJly slaked in our slaking-machine, so as, to form a lime uttyor paste, in which the lime-putty thereby' produced is screened and strained, so as to rid it of all unslaked or objectionable matter, and stored in vats in the ground, therebyremovin all Weight from the building, for a perio of time-preferably from tento fourteen'days-sufficient to insure its slow but thorough slaking and digestion, it finally becoming cold, after which it is mixed With sand 'and ber, thereb producing a roduct which can convenient y be used both or mortar for purposes of laying brick and mortar for -plasterlng 'purposes'.

In the accompanying drawings we have represented a three-story concrete-basement building conveniently adapted for our apparatus.

Fig. 3 represents a vertical section of the complete plant. Fig. 4 represents the plan of the first floor, containing the slaking-tank. Fig. 5 represents a floor plan ofthe second floor, showing ,the

Water-tank and mixing-tank, also the loading-bins-for loading the delivery-wagons with the'finished product. Fig. 6 represents the third floor of said building, containing the sand-screen. Fig. 7 representsa spiral conveyer for conveying the crushed lime to the. bucket conveyer to be conveyed to the slaking-tank. Fig. 8 represents the-lower porytion of the bucket-lift for conveying the sand to the third floor' of said building screened before mixing and also the means for vloading said buckets. Fig. 9 represents in perspective a slaking and mixing machine,y parts being broken away; and Fig. 10 is a detail view showing the lower end of one of the mixing-paddles.

We preferably select a site conveniently located on a sidel track of a railroad, as represented lin Fig. 1.

A, Fig. 1, represents a car unloading lime. By any convenient method the lime is unloaded from car A through the chute B into the lime-crusher C. The lime-crusher com-l prises any suitable means for reducing lime to as small particles as possible. D represents a bin in the ground for holdin and storing the crushedlime. The crushe lime is deposited from the crusher on the inclined' floor D of bin D, down which it descends/by gravity to the s iral conveyer E. (More fully shown in Figf. The spiral conveyer E is ofthe ordinary form. The crushed lime is then conveyed by the conveyer E to to be the endless bucket elevator F, by which it is conveyed to the chute G, which discharges into the slaking-tank S in Figf'2, located on the irstfloor of the building.` Within the slaking-tank S are stirring-paddles or agitators P. (See Figs. 9 and-10.) As the lime is deposited in the slakin -tank S water is continuously let in throng a faucet W', leading from the water-tank W, as shown in Fig. 3,

and at the same time the stirring-paddles are set in motion by means of the gear w', meshwith gear 'wz on the shaft of the stirrer.

s er the lime is thoroughly s aked, the combination of lime and water is discharged through the opening H, as shown on Figs. 2 and 9, by means of a slide-gate H' and handle h, through the chute H2, and throughthe screens S and chutes S2, as fully shown on Fig. 4, into the storage-bins fi, Fig. 2, located in the cellar, where the lime-putty is stored and permitted to remain in bulk for a period of time suflicient to allow it to digest thoroughly and slowly, the lime settling in the bins, leaving the water on the' top to be pumped oil later.

The gravel separated by screen X rolls. own

into a bin X2. The rotary screen J K is any convenient screen, preferably one divided sectionallly, as shown, so that the diferent gradesl of gravel and sand may be distinctly separated, division J screening the sand and division K screening what is commonly known as the roofing-gravel, and the lar er stones or what is known as concrete-grave rolling out through the open end of the screen K, Fig. 2, all into conveniently-located bins for receiving the same until carried off by the delivery-wagons. The sand screened by division J, Fig. 2, is stored in the bin L directly under it, Fig. 2, preferably a bin large'I enough full of the finished product.

to hold enough sand to convenient accommodate enough lime to Vmix one mixing-tank The bins I I I I, ig. 2, for holding the limeputty are four separate bins, all having gates or doors 11' leading into the chute Z. The limeutty contained in one bin is being thoroughly digested While the lime-putty of another bin is being used. The gate leading from the bin about to be used is raised, allowing the utty to `V`escape into the chute Z, where it s up the buckets on the conveyer Q Q, by which it is conveyed to the bin Y, Fig. 2, which bin is located on the second floor and constructed to hold sufficient limeishe putt for the mixing of a tank full of the iindr roduct. lThe ate of the bin Y (see Fig'. 5l) is then opened and the lime allowed to esca e through chute Y into the mixing-taal? M, also on the second floor. The mixing or stirring paddles M are then set in motion. Suiiicient sand is then let in the mixing-tank through chute L from the bin L, Fig. 2, and when plaster fiber is to be mixed the operator in char e throws in a suilicient amount of fiber. T e lime, fiber, and sand are then thoroughly mixed until the inished product is produced, the operator knowing when the mixture has proceeded far enough, after which it is discharged through chute Ml into the storage-tank T, from which the delivery-wagons are lled. `We prefer to use two mixers M and two storage-tanks T, as shown in Fig. 5.

The shafting and gearing for driving the endless carriers, rotary screen, mixers, &c., are not described herein, as they are of an usual construction and arrangement.

Having thus described our invention, what we claimvas new, and desire to'secure by Letters Patent, is-

In a mortar-mixing apparatus, a lime-slaking tank, a series of storage-bins arranged below said tank and into 'any one of which the contents of said tank may be discharged, a central compartment around which all of the bins are grouped, valved discharge-openings leading from said bins into said compartment, an elevated measuring-tank, a conveyer for raising the slaked lime from said compartment to said -measuring-tank, an elevated sand-measuring bin, means for depositing sand therein, a mixing-tank, and chutes leading from both measuring-tanks to said mixin -tank.

testimony whereof we affix our signatures in the presence of two witnesses.
